J.League designated special players

This is a list of J.League designated special players, picked by J.League clubs from universities and high schools all over Japan.

System information
The system, in place since 1998, aims to provide high potential players "a suitable environment in accordance with the player's ability." Most young players are registered with their university or high school until they are at least 18 and as such cannot be registered with another team. The 'designated special players' system allows J.League clubs to invite a maximum of three players to train and play in J.League competitions, without changing their registration status from their current registered team. Therefore, during this time, the player is allowed to play for both their educational institution and their J.League club. This provides the players an opportunity to train and play at a higher level, whilst also giving the clubs an opportunity to sell themselves as a potential destination upon completion of their studies. Although most of the time players go on to sign a professional contract with their host club, there is no guarantees or assurances that it will always be the case.

A player is eligible to become a designated special players if they fulfill the following requirements:
 * They have an official offer from a J. League club
 * They have Japanese citizenship or do not apply as a foreign player
 * They registered with teams under the Japan University Football Association, the All Japan High School Athletic Federation, or teams of the Japan Club Youth Federation Level 2 other than J.League club teams.

Once approved, the players can then participate in any of the following competitions:
 * J1, J2, J3 League matches
 * League Cup matches
 * Pre-season matches
 * J.League promotion/relegation play-off matches
 * Other official matches organised by J.League and the Japan FA
